Abstract
A device with a first MEMS device and a second MEMS device is disclosed. The first MEMS device is configured to sense at least one external influence. The second MEMS device is responsive to the at least one external influence. The first MEMS device is configured to change a state when the at least one external influence exceeds a threshold value. The first MEMS device is configured to retain the state below the threshold value, wherein the change in state of the first MEMS device is done passively and wherein the state of the first MEMS device is indicative of a status of the second MEMS device. In one example, the first MEMS device further comprises a normally open switch that closes when the external influence exceeds the threshold value.
